LOL - see the workaround at the end of this Sage KB entry:
Sales orders do not collate properly when printing multiple sales orders through Multi Part Printing
Entry Type: Program Issue
Defect: 95530
Product:
Sage MAS 90 ERP
Sage MAS 200 ERP
Application: Sales Order
Version Reported: 4.40.0.2
Status:
This is working as designed
Subject:
Sales orders do not collate when printing multiple sales orders to through Multi Part Printing
Steps to Duplicate:
In [ABC] company:
Create two sales orders in Sales Order Entry
Click on Sales Order Printing, enable Multi Part Printing and create multi part copies
Enable Shadow text and enter COPY 1 for the first printer and COPY 2 for the second printer
Accept your settings and print the sales orders
Notice that the output is Sales Order 1 COPY 1, Sales Order 2 COPY 1, Sales Order 1 COPY 2, Sales Order 2 COPY 2
Behavior:
Each line in Multi-Part From Maintenance is a different printer and is handled by Windows that way. Even if all the lines in the grid are pointed to different trays on the same printer they will be handled like individual print jobs. They cannot be collated together.
Possible Workaround:
Collate the print jobs by hand after printing.
